Generalized dynamics of moving dislocations in quasicrystals
, 2010 A theoretical framework for dislocation dynamics in quasicrystals is provided according to the continuum theory of dislocations. Firstly, we present the fundamental theory for moving dislocations in quasicrystals giving the dislocation density tensors ...

Quantum transport in quasicrystals and complex metallic alloys [PDF]
, 2007 The semi-classical Bloch-Boltzmann theory is at the heart of our understanding of conduction in solids, ranging from metals to semi-conductors. Physical systems that are beyond the range of applicability of this theory are thus of fundamental interest ...

Aramid Nanofiber Aerogels: Versatile High Complexity Components for Multifunctional Composites
Advanced Materials, EarlyView.Different forms of aramid nanofibers (ANFs) and especially aerogels from them, offer a sustainable route to high‐performance biomimetic nanocomposites. Due to the cartilage‐like architecture, ANF‐based materials enable breakthroughs in energy, electromagnetic, biomedical, and water purification technologies.

Indagationes Mathematicae (Proceedings), 1987 In two previous papers [ibid. 43, 39-52 (1981; Zbl 0457.05021), 53-66 (1981; Zbl 0457.05022)] the author introduced the concept of a Poisson comb, a Dirac comb where Fourier transform is again a Dirac comb. Analogies between this concept and that of quasicrystal are pointed out.

Quantum cluster quasicrystals [PDF]
Physical Review B, 2020 Quasicrystals remain among the most intriguing materials in physics and chemistry. Their structure results in many unusual properties including anomalously low friction as well as poor electrical and thermal conductivity but it also supports superconductivity, which shows that quantum effects in quasicrystals can be quite unique.

Quasicrystals - Discovery, Structure and Properties [PDF]
Kemija u Industriji, 2012 Quasicrystals are solid materials the structures of which can have crystallographically forbidden symmetries, e.g. of the fifth order, and do not have the translational invariance charactistic for classical crystals.

New group of stable icosahedral quasicrystals: structural properties and formation conditions
, 2003 Structural studies on the icosahedral quasicrystals in Zn-Mg-Sc, Cu-Ga-Mg-Sc, and Zn-Mg-Ti alloys as well as their corresponding 1/1 cubic approximants, have revealed that these quasicrystals belong to a new structural group similar to Cd-based ...

Advanced Science, EarlyView.Superlattices formed by the co‐assembly of acid‐functionalized block copolymers and zwitterions exhibit tunable morphologies, transitioning from lamellae to cylinders to Frank‐Kasper phases. Zwitterion interfacial localization enhances dielectric constant, mechanical strength, and thermal stability, making these materials promising for soft electronics

Journal of Materials Research and Technology, 2019 Icosahedral Al65Cu23Fe12 and decagonal Al73Cu11Cr16 quasicrystalline powders were synthesized by the mechanical alloying and subsequent annealing. Morphology evolution at mechanical alloying of Al-based powders was found to be determined by competition ...
